Sorry for a vague reply, but it's been a while since I've had to deal
with windows. But the term MTU seems to be dimly lighting some bulbs
over my head, so see http://support.microsoft.com/kb/q140375/

and search metalink on:
network sqlnet MTU
(as well as the notes for sqlnet tracing, and the docs for trcasst).

My vague memory is there was some mismatch in the defaults of how big
the packets were so I needed to tell one of the machines to use larger
packets and not believe the discovery of maximum size, or something
like that.
